Setting up a test server for my girlfriends business… quick questions

Girlfriend and her business partner want a website so I thought I would show them a couple wordpress/joomla templates they could do on the cheap.

I have a server I run at my place with windows server 2012 r2 that I put both joomla and wordpress on. I’ve bought the domain and pinging the domain I get a reply from my external ip address. The router is setup to forward port 80 to the server’s (static) Ip address.

On the server if I go to localhost it goes to windows server r2 essentials remote web access.

There must be something I need to change. Does anyone know what’s going on here?
